The O2NE+ Laboratory Oxygen Monitor provides two audio visual alarms which are pre-set at 19.5% & 18% (but can be adjusted) to warn personnel of a potential leak which may cause the O2 levels to deplete to a dangerous level. Complete with a 7 years sensor lifespan.

The O2NE+ main sesnor unit is wall mounted at normal working head height in the area/s recommended as a result of risk assessment. The repeater unit/s are then sited at the entrance/s to the area to let staff or visitors know if it is safe to enter or not.

A certified calibration gas must be passed over the sensor at 18 month periods.  This is a safety feature which prevents a potentially false calibration being made.
